The AD7175-2 is a 24‑bit Σ‑Δ ADC offering up to 250 kSPS output rate, 20 µs settling time and rail‑to‑rail input buffers.
The AD7175-2 is a low‑noise, fast‑settling, 2‑ or 4‑channel Σ‑Δ analog‑to‑digital converter. It provides selectable output data rates from 5 SPS to 250 kSPS, a 24‑bit resolution, and rail‑to‑rail input and reference buffers with ±1 ppm INL when enabled.
Typical applications include process control, temperature and pressure measurement, medical and scientific instrumentation, and chromatography. The device is supplied in a 24‑lead ultra‑thin TSSOP package and operates from 4.5 V–5.5 V (AVDD1) and 2 V–5.5 V (AVDD2/IOVDD) over a temperature range of –40 °C to +105 °C.
